Swift: Back button should be pressed twice while SearchBar is active

Question

I have a UITableViewController embedded in a navigation bar and standard Search bar implementation. I don't hide the navigation bar while the search bar is active. The problem is that while the search bar is active, every button in the navigation bar, like a "Back" button, should be pressed twice— the first time to make the search bar inactive. How can I avoid that? Thank you.

在viewDidLoad

上添加此代码

    self.definesPresentationContext = true

如果您的navigationBar是Opaque

，请添加此项

    self.extendedLayoutIncludesOpaqueBars = true
